About

Rapid maxillary expansion and quad-helix are two well established appliances in dentistry used for posterior cross bite treatment. This study aims to compare this two different appliances in patients in their early mixed dentition, regarding treatment effects of the extra oral soft tissue but also dental and skeletal effects, if the children experience any pain and discomfort during treatment and the study also aims to make a cost minimization analysis. Comparison of these different treatments are barely made and no randomized controlled trial is yet published. No study has evaluated the difference of subjective experience during these two treatments. After this study we will know which one of these two appliances are the most effective, regarding cost minimization and treatment result but we are also able to put it in relation to the patients subjective experience
